Watching an iPhone Feud on ‘The Daily Show’

As the Internet works its way further into pop culture, sites like YouTube and Twitter pop up more and more in the routines of late-night shows like Conan O’Brien, Jimmy Fallon and last night, David Letterman and Jon Stewart. Digits can’t get enough of ‘em.

In a segment called “iFeud,” Wyatt Cenac, a correspondent for “The Daily Show With Jon Stewart,” talks to the creators of the rival iPhone apps iFart and Pull My Finger.

The app got as high as No. 2 on Apple’s iTunes App Store and was bringing in more than $10,000 a day, Mr. Cenac tells a snickering “Daily Show” audience.

Wyatt Cenac of the “Daily Show” keeps a straight face during an iFart demonstration.

But then Infomedia launched iFart in the summer of 2008, which knocked it from the charts and remains so popular that it’s triggered a flurry of similarly named copycats.

“IFart’s a superior product because of the utility features that are built into the application,” says Infomedia’s Joel Comm.

The two bodily-function-software purveyors go back and forth (“IFart ripped me off,” Stratton says. “They wanted somebody to blame,” Comm says.), but the must-see moment occurs around 3:20, when Mr. Stratton compares his struggle to that of Jackie Robinson.
